“…Recently, we developed a theoretical model of interference microscopy imaging to provide analysis of the imaging process of different types of samples in different types of interference microscopes [13][14][15]. Basing on this theory, we propose in the current paper a numerical processing technique, which is intended to overcome the problems of coherence gate fading in confocal OCM imaging and allow fast three-dimensional imaging of samples, which may consist of layers with different refractive indices, unequal to the refractive index of immersion.…”

Along with high longitudinal resolution of optical coherence tomography, confocal optical coherence microscopy (OCM) provides high transversal resolution due to relatively high numerical apertures. However, the presence of relatively high numerical apertures leads to limited depth of field, which reduces the speed of OCM and decreases the advantage of Fourier domain detection. In this paper we propose a numerical processing technique for three-dimensional image reconstruction in Fourier domain OCM. It takes into account not only the defocus of different parts of imaged volumetric sample, but also the effects of upper layers’ refractive index on imaging the sample inner structure. Besides providing sharp coherence gated imaging, this technique also allows for determining both the geometrical thickness and refractive index of the sample layers.
